Thank you for the suggestion -- but this is NOT the case here.

I'm well acquainted with Suspend - it has effects which interfere 
with how I use my XO - so after installing I always do both 'touch 
/etc/ohm/inhibit-idle-suspend' and 'touch /etc/inhibit-ebook-sleep'. 
And my Power LED is on steadily -- showing I'm not in suspend.

The sluggishness is not consistent.  I particularly notice that at 
times, it can take more than three seconds before the XO responds to 
an alt-tab (after a period without any key presses).  This XO has a 
background (nice 19) task running on it which consumes 100% of the 
available CPU cycles -- I'm wondering if there is some kind of 
keyboard service which expects the CPU to be "free" sometime?
